Hi Downunder1
I've checked the serial number linked to your Forum log in. Company file ID 7 is online and is using an STP entitlement. To check the Company File ID go to Help>>About MYOB AccountRight.
As mentioned by gavin12345 , if you have been accessing this file offline (locally) you will need to take a back up of the current offline file and restore it online. You will then be able to transition to STP Phase 2.
You can tell which phase you're on in the STP reporting centre. If you're on Phase 2, in the top right corner will be a label Reporting on STP Phase 2 and there's also a Send update event button.
Let us know if you need further help.
